Under the Trump EPA, no risk to workers is too high to impede a new chemical’s unfettered entry into the market

Richard Denison, Ph.D.is a Lead Senior Scientist.

The Trump EPA’s understating of the risks to workers posed by both existing and new chemicals under the Toxic Substances Control Act (TSCA) has been a frequent topic for this blog.  This disturbing, illegal policy continues unabated and, if anything, has accelerated and expanded to outright dismissal of worker health concerns.

The Trump EPA’s blatant shirking of its clear responsibilities under TSCA to identify and mitigate the serious risks that chemicals present to workers – who are on the front lines of chemical exposures – surely constitutes one of its most egregious failings.

In its reviews of new chemicals, EPA now frequently identifies serious risks to workers that exceed its own risk benchmarks, often many times over.  How great are the exceedances EPA finds and ignores?  Our examination of recent cases, described below, reveals exceedances as high as 25,000-fold.  In other words, EPA has found and then dismissed worker exposures to new chemicals at levels as much as 25,000 times higher than it deems acceptable. That is not a typo:  In a very recent case EPA found a dermal risk of reproductive effects to workers that exceeded its own benchmark by a factor of 25,000.

Any reasonable new chemical review that identified excess risk would then impose conditions blocking or conditioning the market entry of these chemicals in a manner sufficient to mitigate the identified risks.  Indeed, that is exactly what TSCA requires EPA to do.

Instead, the Trump EPA over and over again clears these chemicals entirely, ignoring its own risk findings to assert that the chemicals are “not likely to present unreasonable risk.”  This has now been done for hundreds of new chemicals EPA has reviewed in the past two years.

To illustrate what EPA is doing, we examined the 29 new chemicals EPA found “not likely to present unreasonable risk” (“not likely” determinations) since the beginning of June of this year.  Read More »

EPA flouts the law, science, and its obligation to protect public health yet again: The 1-bromopropane final risk evaluation

Richard Denison, Ph.D.is a Lead Senior Scientist.

Today, the Trump EPA released its second final risk evaluation and determination under the reformed TSCA, for the carcinogenic solvent, 1-bromopropane (1-BP).

EPA has once again ignored expert scientific input it received from its own advisors.

As was the case with the final document for methylene chloride – which has already been challenged in court (see here and here) – EPA has doubled down on the illegal, unscientific, and un-health protective approach it has taken in all of its draft risk evaluations for the first 10 chemicals reviewed under TSCA.

EDF will be closely examining this final document, but it is already apparent that EPA continues to grossly and systematically underestimate the exposures to and risks of 1-BP to the general public, workers and the environment.

Below are four examples of the flaws; each was raised by EPA’s own Science Advisory Committee on Chemicals (SACC) in its peer review as serious deficiencies – expert scientific input that EPA has simply chosen to ignore in finalizing the document:  Read More »

“Illegal, unscientific, and un-health protective”: Summing up EPA’s final methylene chloride risk evaluation

Richard Denison, Ph.D.is a Lead Senior Scientist.

Today, the Trump EPA released its first final risk evaluation and determination under the reformed Toxic Substances Control Act (TSCA), for the carcinogenic and acutely lethal chemical methylene chloride.

Sadly, despite EPA’s rush to issue this document as the 4th anniversary of TSCA reform on June 22 approaches, EPA doubled down on the illegal, unscientific, and un-health protective approach it has taken in all of its draft risk evaluations for the first 10 chemicals reviewed under TSCA.

EDF will be closely examining this final document, but it is already apparent that EPA has grossly and systematically underestimated the exposures to and risks of methylene chloride.  Read More »

EPA’s own words reveal what its new chemicals program has become – a captive of industry

Richard Denison, Ph.D.is a Lead Senior Scientist.

“The agency’s goal is to allow the commercialization of products,” said EPA associate deputy assistant administrator for new chemicals Lynn Dekleva.

Readers of this blog know that EDF is no fan of how the Trump EPA has implemented – in our view, twisted – the 2016 reforms made to the review process for new chemicals under the Toxic Substances Control Act (TSCA).  Decision after decision over the last 3.5 years under this administration has undercut public health and benefitted industry interests, despite some noble efforts by career staff to chart a better course.  In recent weeks the Trump EPA’s intentions have been even more clearly revealed, thanks to the trade press’s reporting of EPA political appointees’ comments delivered to industry audiences.  That’s what this post is about.  Read More »

Reveal News exposes Trump Administration’s disregard for protecting the public from a highly dangerous chemical: 5 key takeaways

Richard Denison, Ph.D.is a Lead Senior Scientist.

This weekend, Elizabeth Shogren at Reveal News published an in-depth investigative report and hour-long radio segment delving into the Trump EPA’s latest abandonment of science and its serious consequences for public health.  The story focuses on the ubiquitous solvent trichloroethylene (TCE), a known human carcinogen and neurotoxicant that is also linked to birth defects at very low levels of exposure.

In reforming the Toxic Substances Control Act (TSCA) in 2016, Congress directed EPA to conduct comprehensive reviews of the risks posed by TCE and other widely used chemicals.  EPA was charged with identifying risks both to the general public and to “vulnerable subpopulations,” including pregnant women, infants, workers, and others.

EPA’s draft risk evaluation of TCE was released on February 21.  It suffers from many of the same gaping flaws as do EPA’s draft risk evaluations for other chemicals.  Once again, EPA has utterly failed to carry out the clear intent of the law, putting our health at greater risk.

  • EPA has ignored all exposures of the general population to TCE that arise from releases of the chemical to air, water and land – amounting to millions of pounds annually.
  • EPA has once again assumed, without any supporting data, that workers will wear personal protective equipment and that it will be effective in eliminating or reducing exposures.
  • EPA has inflated the acceptable level of risk of cancer that will allow workers to be exposed to as much as 100 times more of the chemical.

“This decision is grave. It not only underestimates the lifelong risks of the chemical, especially to the developing fetus, it also presents yet another example of this administration bowing to polluters’ interests over public health.”

Dr. Jennifer McPartland

But in this new draft EPA has gone even further in abandoning both science and the law.  Reveal’s exposé identifies key changes made at the 11th hour to the draft that were forced on career staff at the agency by the White House.

Here are five key takeaways from the Reveal story:  Read More »

EPA’s draft risk evaluation of carbon tetrachloride is riddled with unsupported exclusions and assumptions

Richard Denison, Ph.D.is a Lead Senior Scientist.

Next week, the Scientific Advisory Committee on Chemicals (SACC), established under the Toxic Substances Control Act (TSCA) to peer-review EPA’s draft chemical risk evaluations, will meet to review the latest of those drafts, for the likely human carcinogen carbon tetrachloride.

As with other recent draft risk evaluations, EPA has been scheduling the SACC meetings in the middle of rather than following the public comment period.  This means the public has at best a few weeks to digest these huge documents and draft and submit comments in order to have them be part of the record that the SACC is allowed to take into consideration in its peer review.

However, we have learned that EPA is now further constraining the SACC’s schedule, requesting that the panel members come to the peer review meeting with their comments already drafted, and then delivering their final report within 60 days rather than the 90 days previously provided.  These developments further jam both the public and the SACC in their efforts to ensure EPAs work is subject to a robust peer review.

Whatever the reasons for EPA making these changes, EDF decided to expedite our initial comments to seek to ensure they could be considered.  We submitted comments last week, a full week before the February 19 deadline, to ensure the SACC received and had sufficient time to review them in advance of the peer review meeting.

We deemed this critical because of the glaring gaps and flaws in EPA’s draft that lead it yet again to drastically understate the risks of this chemical.  These include the same problems that have plagued the draft risk evaluations for other chemicals, as well as new ones.  Read More »
